Not sure about debug info, but the (linker) symbol has a "@number" suffix
appended. A.k.a., "decoration". Like "symbol@4".
In gcc/config/i386/winnt.c:
/* Return string which is the function name, identified by ID, modified
with a suffix consisting of an atsign (@) followed by the number of
bytes of arguments. If ID is NULL use the DECL_NAME as base. If
FASTCALL is true, also add the FASTCALL_PREFIX.
Return NULL if no change required. */
static tree
gen_stdcall_or_fastcall_suffix (tree decl, tree id, bool fastcall)
{
As you see above, fastcall also has identifiable decoration.
I don't recall the rules or conditions of when the decoration is
stripped or not anymore.
See e.g., http://stackoverflow.com/questions/8063842/mingw32-g-and-stdcall-suffix?rq=1
